Weather maps are used to show current conditions and predict future weather. Different symbols on maps represent cold and warm fronts, high and low pressure systems, and other conditions. Cold fronts bring stormy weather as warm air is lifted, while warm fronts move slowly and bring steady precipitation. Stationary fronts occur when neither air mass can replace the other, bringing long periods of clouds and rain. High pressure is associated with clockwise winds and fair skies, while low pressure brings counterclockwise winds and storm formation.
What is greenhouse effect ?
Is greenhouse effect have a serious impact on human health?
What we have to do to reduce the greenhouse effect ?
This simple presentation helps to understand the basic facts about greenhouse effect.
Climatology is the science of studying the average atmospheric conditions of a region in long-term perspective. The primary goal of Climatology is to study the unique characteristics of atmosphere in controlling the global climate, origin, types of climates, causes and processes influencing the climatic variations, elements of weather and the impact of climate on humans or vice-versa.

2. *Weather maps are used to show
current weather conditions in an effort
to predict future weather conditions.
*You need to know what each symbol
means and how to interpret them to
forecast the weather.
3.
4. *Cold, dense air is moving toward warm, less dense air.
*The warm air is pushed up to cool and form clouds as the
cooler air replaces it.
*The air on the front side of the boundary line is warmer
than the air on the back side of the boundary line.
*These fronts are usually fast moving and bring stormy
weather and heavy precipitation followed by clearing
skies and higher pressure.
5.
6. *Warm air is moving toward cold air.
*The warm, less dense air slides over the cold,
more dense air.
*The air on the front side of the boundary line is
cooler than the air on the back side of the
boundary line.
*These fronts usually move slowly and bring
steady rain or snow over many days.
7.
8. *These fronts occur when neither the
cool or warm air masses are strong
enough to replace each other.
*They tend to stay in an area for a long
period of time, often bringing long
periods of precipitation and clouds.
9.
10. *Cooler, dense air close to the surface
of the Earth.
*Surrounded by winds flowing in a
clockwise direction.
*Usually brings dry conditions and fair
skies.
11. *Let’s practice.
*Remove the lid from the bottle.
*Now, replace the lid.
*What direction did you turn the lid to tighten
it?
*Did the lid move up or down?
*This is a way to remember high pressure.
12.
13. *Warmer, less dense air above the Earth’s
surface
*Surrounded by winds moving in a
counterclockwise direction.
*Associated with the formation of storms.
14. *Let’s practice.
*Remove the lid from the bottle.
*What direction did you turn the lid to
loosen it?
*Did the lid move up or down?
*This is a way to remember low
pressure.

17. Why does the Earth have weather?
How do weather maps show how
global patterns of atmospheric
movement influence local weather?
